HTS possesses depot-level maintenance facilities in several locations in both Canada and the United States, including La Ronge, Saskatchewan; Carp, Ontario; Trois-Rivieres, Quebec; Baltimore, Maryland; and Aurora, Oregon.

With these overhaul capabilities, HTS can maintain, refurbish, repair, and service components for its helicopters on an ongoing basis, avoiding the need to rely on third parties, while also assuring final quality of the work product. The component overhaul processes are Transport Canada- and/or FAA-certified and approved, and are overseen by a dedicated component overhaul staff, whose sole responsibility is the safe, meticulous, and thorough refurbishment of components for return to service.

The newly-constructed HTS facility in Aurora, Oregon is approximately 220,000 square feet (approximately 20,500 square meters; pictured below) dedicated to the ongoing support and maintenance of the HTS Group’s heavy helicopter fleet, such as the CH54B Skycrane.

The Aurora facility features:

Engine overhaul for the JFTD12 engine equipped on the CH54/S64 helicopters;

Hydraulics overhaul facility for the overhaul and repair of hydraulic components such as servos, gear legs, pistons, etc.;

Electrical and avionics shop for the electrical and cockpit systems;

Sheet metal and fabrication shop for airframe and structural repairs;

The largest aircraft paint booth on the west coast of the United States capable of fitting an entire CH54/S64 aircraft;

Over 120,000 square feet (11,148 square meters) of warehouse to store an ample supply of spare components and engines to support the fleet.
